If you open an RDF document that contains some SKOS but doesn't contain an
ontology IRI statement, then the SKOS asserted hierarchy view will throw a null
pointer exception. This is because the underlying SKOS API assumes all files
loaded will have an ontology IRI specified.
This will get fixed in the SKOS API and moved to the plugin in the next
release. In the meantime, if you are struggling to load a SKOS file, try giving
it an ontology URI, then reloading it.
